problem with select

[Former Member]

see the below code all the selects and locking are happening on the same table xxxxx.

SELECT * FROM xxxxx

INTO TABLE i_vbeln

WHERE vbeln IN s_vbeln

AND bukrs IN s_bukrs

AND vkorg IN s_vkorg

AND vkbur IN s_vkbur

AND vkgrp IN s_vkgrp

AND auart IN s_auart.

if sy-subrc = 0.

LOOP AT i_vbeln.

CALL FUNCTION 'ENQUEUE_EXXXXX'

EXPORTING

mode_zse32 = 'X'

mandt = sy-mandt

vbeln = i_vbeln-vbeln

EXCEPTIONS

foreign_lock = 1

system_failure = 2

OTHERS = 3.

IF sy-subrc EQ 0.

*SELECT SINGLE FOR UPDATE **

FROM xxxxx

INTO i_vbeln

WHERE vbeln EQ i_vbeln-vbeln.

xxxxxxxxxxxxxxxxx

xxxxxxxxxxxxxxxxxxxx

xxxxxxxxxxxxxxxxxxxx

xxxxxxxxxxxxxxxxxxxxxx

xxxxxxxxxxxxxxxxxxxxxx

CALL FUNCTION 'DEQUEUE_EXXXXX'

EXPORTING

mode_zse32 = 'X'

mandt = sy-mandt

vbeln = i_vbeln-vbeln.

endloop.

endif.

now my question is..

is it mandatory to have the the below select for updating the table xxxxx

*SELECT SINGLE FOR UPDATE **

FROM xxxxx

INTO i_vbeln

WHERE vbeln EQ i_vbeln-vbeln.

or can i go directly with enque and deque without the above select before updating the table

hi,

You can just call FM ENQUEUE_E_XXXX and DEQUEUE_E_XXXX for locking and unlocking the tables with out any select statements ..

enque BEFORE you do your select thats essential.
